Explain to me like I'm an Atlanta Public Schools grad the difference between the Kuchera and 10:1 snowfall models.

Kuchera ratio is a more accurate method of determining snowfall amounts. I think it can take into account temperature and mixing due to warm noses. Snowfall is generally estimated to be at a 10:1 ratio of snow to liquid equivalent, whereas more marginal temps can lead to ratios of 8:1 or colder temps up to 20:1. The kuchera ratio should take this into account.
- From Reddit
I know the 10:1 ratio was discussed a lot with our snow last week, essentially that NWS was estimating it closer to 7:1. It sounds like it's pretty common for them to question 10:1 ratios in our area just on account of how often/common it is for it to be a razor thin margin between all liquid, mixed and frozen.

My basic understanding:
10:1 is a rain model that just assumes a 10x rain multiplier for snow volume.
Kuchera is actually a snow model.
But supposedly the net and gross snow depth models are historically better predictors, especially with mixed sleet and ice.
And plenty of runs the last week it'll show 0" snowfall but like 6" accumulation and vice versa. They're not internally consistent.

Are we officially to the point where we bring up your boy in Josh whatever his name is from the station in BR last time we had snow arguing with people on Facebook about snow being fake and any reports incorrect while people are literally posting pictures of themselves sitting in snow around town?

12.5"?? I'd need 3 tries to measure that.

was reading about 1895 the other day. They claim 22" in Houston i don't know how that's possible other than the mythical Gulf of Mexico effect snow
Reading about the atmospheric set up for that event, looks very similar to this one. Artic blast coming in with a low pressure strengthening in the Gulf of America moving inland…not saying we getting 24” though. I can’t even imagine what that would be like down here

Also Global Warming wasn't a thing in 1895 so we have nothing to worry about.

One day you wake up and it starts snowing. No weatherman or nothing. Wild.

They knew it was coming when the church elders reported aching joints.

Losing electricity and 17 degrees isn’t something that I’m looking forward too. I am breaking out the he generator. I have a 7250 with 8000 max. If I only ran my central heater at night would my generator run it? It’s a 5 ton system.

Gas furnace? or is the whole system electric?

The state record is 24" in Rayne in 1895 so its possible....lol
I may be wrong but I thought the state record was in Oberlin.

I’m pretty sure it was closed due to the snow/ice in Jan 2018. I was commuting from Prairieville to Nola at the time and remember missing a couple days of work.
